Why in News:

  • The official of the Anamalai Tiger Reserve (ATR) praises the ICAR-Sugarcane Breeding Institute for its tribal development initiatives.

About:

  • Originally named Anamalai Wildlife Sanctuary, it was renamed Indira Gandhi Wildlife Sanctuary and National Park before becoming the Anamalai Tiger Reserve in 2008, when Project Tiger was established.
  • The Tamil Nadu part of the Anamalais is home to Anamalai Tiger Reserve (in Kerala and Tamil Nadu).
  • The reserve’s Tamil Nadu section is known as ATR. It is located in the Southern Western Ghats, south of the Palakkad Gap.
  • Dry deciduous forests, semi-evergreen forests, evergreen forests, and wet temperate forests all thrive here.
  • Annual Rainfall – 500 mm to 5000 mm, with the eastern slopes receiving the least rainfall and the western slopes receiving the highest.
  • Elephants, Gaurs, Water Buffaloes, Tigers, Panthers, Sloth Bears, Pangolins, Black-Headed Orioles, Crocodiles, Green Pigeons, Civet Cats, Dholes, Sambars, and 31 endangered wildlife macaque groups are various animals found here.
  • Pied Hornbill, Red Whiskered Bulbul, and Drongo are three bird species.
  • The Malasar, MalaiMalasars, Kadars, Eravallars, Pulayars, and Muduvars are among the indigenous peoples that live in Animals, and it is worthy of being declared as an “Anthropological Reserve.”

e-DNA Methodology

Why in News:

Two separate studies have shown that DNA floating in the air may help conserve biodiversity worldwide.

About e-DNA Tech:

  • Animals release DNA into the environment via their breath, saliva, hair, and feces. These DNA strands are dispersed around in the air.
  • Environmental DNA refers to the DNA found in the air (e-DNA).
  • Animal tracking by e-DNA is not a novel concept. By sequencing e-DNA from water samples, biologists were able to see aquatic species.
  • Similarly, the two teams used sensitive filters coupled to vacuum pumps to filter e-DNA from the air.
  • After collecting DNA from the air, the scientists used a polymerase chain reaction to make copies (PCR). DNA sequencing was the last stage.
  • The animal was subsequently identified by comparing the sequencing data to known sequences.
  • These e-DNAs have the potential to be utilized to identify and track terrestrial animals.
  • Their results might aid in deciphering animal community makeup and detecting the spread of non-native species.
  • However, the e-DNA technology, in its present state, is unable to produce reliable data for population census. It will, however, in the future.

Molnupiravir, an anti-Covid drug, has been approved but is not advised.

What is the News?

  • The medicine Molnupiravir, which was recently licensed for early-stage Covid-19 patients, has been excluded from the Indian Council of Medical Research’s recommended treatment strategy.
  • This is due to major worries about the drug’s safety.

What are the risks linked with the medicine Molnupiravir?

  • In studies, the medicine was shown to be just 30% effective, which is much lower than previous indications.
  • The drug operates by embedding itself into the virus’s RNA, causing mutations with the goal of preventing reproduction.
  • However, doing so runs the risk of introducing mutations into the virus, making it stronger and more lethal. The medicine has a greater risk of causing mutations in human DNA.
  • The medicine has the potential to induce teratogenicity (the propensity to cause birth abnormalities in a growing foetus), cartilage damage, and muscle damage.

Ministry of Earth Sciences: Year-End Review for 2021

Context:

  • In the year 2021, the Ministry of Earth Sciences has initiated a number of projects.

About Various Initiatives:

Earth System Science Data Portal:

  • The Ministry of Earth Sciences created the Earth System Science Data Portal (ESSDP). It is a MoES institutions’ integrated digital online platform that makes data on numerous issues of earth system science accessible for public use.

Atmospheric Research Testbed:

  • The Atmospheric Research Testbed is an open field observatory in Madhya Pradesh that uses state-of-the-art observational systems such as radars, wind profilers, and unmanned aerial vehicles (UAVs) to better understand the processes governing monsoon convection and land-atmosphere interactions over the core monsoon region.

Indigenous Decision Support System

  • The Indian Institute of Tropical Meteorology (IITM) created the Indigenous Decision Support System for enhanced air quality management in the Delhi NCR area.

High-Resolution Rapid Refresh: 

  • HRRR model is an hourly-updating atmospheric predictions model with a high frequency of updates over the next 12 hours. It covers the whole Indian continent, with weather predictions every two kilometres in all regions.

Water Quality Buoy:

  • The National Centre for Coastal Research (NCCR) has put a water quality buoy in the coastal waters off Puducherry.
  • This is a sensor-equipped automated water quality buoy that monitors changes in the water quality and productivity of coastal waterways.

Indian Ocean Data Portal

  • INCOIS, in collaboration with NIOT and PMEL-NOAA, established the Indian Ocean Data Portal.
  • It will have a huge collection of meteorological and oceanographic data sets, as well as direct access to data presentation and delivery.

Deep drilling in Maharashtra’s Koyna intraplate seismic zone

  • This project was authorised in 2013 for scientific deep drilling in Maharashtra’s Koyna intraplate seismic zone.
  • It will be a once-in-a-lifetime chance to learn more about the mechanics of reservoir-triggered earthquakes.
